Thanks, y'all. I do appreciate it. I've been sitting here second guessing myself since before Christmas. Did I wait too long, did he have more time, should I have had the tumor removed instead, would he have survived the surgery?
I have to believe the cold snap closing my new vet the day it was supposed to happen and then seeing that his old vet's office was reopening with a new vet to do as-needed services and his old vet doing end of life services for Peaceful Passings was the sign I needed that I was doing the right thing at the right time.
